McDaniel over the weekend gave Day (pictured above on the left) the opportunity to either back Trump or resign, but Day refused to support the GOP nominee, according to the Detroit Free Press.
"It is important for our party to represent all of the voices in our party, not just the loudest," Day, said in a letter sent to the Detroit Free Press. "Therefore, I am not resigning."
Day was elected to her position in the Michigan GOP at a state convention last year, and supported Sen. Ted Cruz's (R-TX) presidential bid. And she's since become an outspoken critic of Trump, according to the Detroit Free Press.
